[0036] Please see Figure 1 and Figure 2 The dustproof device provided in the embodiments of this application will now be described. The dustproof device provided in the embodiments of this application includes a mounting frame 1, a flexible cover 2, and a guide wire 3. One end of the flexible cover 2 is connected to the mounting frame 1, and the other end of the flexible cover 2 is connected to an external moving part. The flexible cover 2 is used to cover the component between the mounting frame 1 and the external moving part. The guide wire 3 is fixed to the mounting frame 1 and passes through the flexible cover 2 and the external moving part.
[0037] The dustproof device provided in this application embodiment is suitable for protecting the precision components of equipment (such as linear guides, linear motors, gratings, etc.) from contaminants such as dust, particles, and debris.
[0038] Mounting bracket 1 is a fixed support structure for the dustproof device, used to securely install the dustproof device onto the laser processing equipment. Mounting bracket 1 may include a left mounting plate and a right mounting plate, which are respectively positioned at both ends of the movement path of the external moving component. One end of the flexible cover 2 is connected to either the left or right mounting plate, and the other end of the flexible cover 2 is connected to the external moving component. The left and right mounting plates have multiple mounting holes for fixing them to the base or frame of the equipment using bolts or screws. Mounting bracket 1 is typically made of high-strength metal materials (such as aluminum alloy or stainless steel) to ensure its structural strength and stability.
[0039] The flexible cover 2 is used to cover the component between the mounting frame 1 and the external moving part to prevent contaminants from entering the precision component area of the equipment. The flexible cover 2 is made of a high-strength, wear-resistant, and corrosion-resistant flexible material, such as polyurethane-coated fabric or flexible rubber. One end of the flexible cover 2 is connected to the mounting frame 1, and the other end is connected to the external moving part, allowing it to expand and contract with the movement of the external moving part. The surface of the flexible cover 2 can be designed to be corrugated or pleated to increase its elasticity and flexibility while reducing resistance during movement.
[0040] The guide wire 3 guides the movement direction of the flexible cover 2, ensuring that the flexible cover 2 remains stable and does not twist or deviate during expansion and contraction. The guide wire 3 occupies little space, making it suitable for compact equipment and improving space utilization. The guide wire 3 is fixed to the mounting frame 1 and passes through the flexible cover 2 and external moving parts. The guide wire 3 can be made of high-strength steel wire rope, nylon rope, or other materials with high tensile strength and low coefficient of friction.
[0041] When an external moving part (such as a slider on a linear motor guide rail) moves, the flexible cover 2 extends and retracts accordingly. Guided by the guide line 3, the movement direction of the flexible cover 2 is ensured to be stable and without twisting or deviating.
[0042] During the expansion and contraction process, the flexible cover 2 maintains its coverage over the precision components of the equipment, preventing contaminants such as dust, particles, and debris from entering the equipment. The corrugated or pleated design of the flexible cover 2 allows it to adapt to the rapid movement of external moving parts, while reducing resistance and noise during movement.
[0043] During equipment operation, the synergistic effect of the flexible cover 2 and the guide line 3 ensures that the precision components of the equipment are always in a good protective state, extending the service life of the equipment and improving the operating accuracy and reliability of the equipment.
[0044] The dustproof device in this embodiment employs a flexible cover 2 and a guide line 3 design, which can effectively protect the precision components of the equipment without increasing the overall size of the equipment. The elasticity of the flexible cover 2 allows it to fit tightly against the surface of the equipment when not in use, reducing space occupation. At the same time, the guide line 3 occupies little space, making it suitable for equipment with compact space and improving space utilization.
[0045] The design of the guide line 3 ensures that the flexible cover 2 remains stable during high-speed movement, without twisting or shifting. The corrugated or pleated structure of the flexible cover 2 can adapt to the rapid movement of external moving parts, reduce resistance during movement, and ensure high-precision operation of the equipment.
[0046] The flexible cover 2 is provided with several sliding holes for the guide wire 3 to pass through, and the edges of the sliding holes are covered with wear-resistant parts.
[0047] The wear-resistant component in this embodiment can be made of wear-resistant rubber or polytetrafluoroethylene (PTFE). The wear-resistant component reduces friction between the guide wire 3 and the sliding hole, extending the service life of the flexible cover 2. The wear-resistant component can be installed on the edge of the sliding hole using adhesives or mechanical fastening.
[0048] Please see Figure 3 , Figure 4 and Figure 5 The dustproof device also includes a fixing component, which is installed on the mounting frame 1 and is used to connect one end of the guide line 3 to fix the guide line 3.
[0049] The fixing component can be an electric winding machine or a winding post inserted into the mounting bracket 1, with the guide wire 3 wound around the winding post. The fixing component can fix the guide wire 3 to prevent it from loosening.
[0050] Preferably, the fixing component includes a mounting part 4 and a first threaded fastener. The mounting part 4 is mounted on the mounting bracket 1. The mounting part 4 is provided with a through hole 41 for the guide wire body 3 to pass through. The side wall of the mounting part 4 is provided with a first threaded hole 42 for inserting the first threaded fastener. The first threaded hole 42 communicates with the through hole 41. The first threaded fastener is inserted into the first threaded hole 42 and abuts against the guide wire body 3.
[0051] In this embodiment, the first threaded fastener can be a screw or a bolt. The first threaded fastener is inserted into the first threaded hole 42 and abuts against the guide wire 3, which can fix the guide wire 3 and prevent the guide wire 3 from loosening.
[0052] The fixing component also includes a second threaded fastener and a third threaded fastener. The side wall of the mounting component 4 is provided with a second threaded hole 43 and a third threaded hole 44 that communicate with the through hole 41. The second threaded hole 43 and the third threaded hole 44 are spaced apart on the side of the mounting component 4 away from the first threaded hole 42. The second threaded fastener is inserted into the second threaded hole 43 and abuts against the guide wire body 3. The third threaded fastener is inserted into the third threaded hole 44 and abuts against the guide wire body 3.
[0053] To further enhance the stability of the guide wire 3, the fixing assembly may also include a second threaded fastener and a third threaded fastener, which may specifically be a screw or a bolt. The second threaded fastener and the third threaded fastener are respectively inserted into the second threaded hole 43 and the third threaded hole 44, and abut against the guide wire 3, thereby achieving multi-point fixing and ensuring that the guide wire 3 will not loosen during operation.
[0054] The dustproof device also includes a tension adjustment component 5, which is mounted on the mounting frame 1 and connected to the fixing component to adjust the tension of the guide wire 3.
[0055] The tension adjustment component 5 is used to adjust the tension of the guide wire 3 to ensure that it maintains appropriate tension during operation, so as to avoid the flexible cover 2 from moving poorly due to insufficient tension or the guide wire 3 from wearing due to excessive tension.
[0056] The tension adjustment component 5 can be a linear motor, which is mounted on the mounting bracket 1, and the fixing component is connected to the linear motor via transmission.
[0057] Preferably, the tension adjustment assembly 5 includes a mounting block 51, an adjusting member 52, and a fourth threaded fastener. The adjusting member 52 is connected to the fixing assembly. The mounting block 51 is mounted on the mounting frame 1 and has a fourth threaded hole. The adjusting member 52 has a waist-shaped adjusting hole 521. The fourth threaded fastener passes through the waist-shaped adjusting hole 521 and is threadedly connected to the fourth threaded hole.
[0058] The fourth threaded fastener can be a screw or a bolt.
[0059] The mounting block 51 can be an L-shaped mounting block, which can be fixed to the mounting bracket 1 by bolts or screws.
[0060] The adjusting member 52 may be provided with mounting holes for installing fixing components, which are inserted into the mounting holes. The length direction of the waist-shaped adjusting hole 521 is parallel to the length direction of the guide wire 3. When the guide wire is fixed by the first threaded fixing member, the second threaded fixing member, and the third threaded fixing member, the tension of the guide wire 3 can be adjusted by moving the adjusting member 52 along the length direction of the waist-shaped adjusting hole 521.
[0061] The tension adjustment assembly 5 also includes a fifth threaded fastener. The mounting block 51 is provided with a fifth threaded hole 511, and the adjusting component 52 is provided with a sixth threaded hole 522. The fifth threaded fastener is threadedly connected to the fifth threaded hole 511 and the sixth threaded hole 522.
[0062] The fifth threaded fastener can be a screw or a bolt. Loosening the fourth threaded fastener and rotating the fifth threaded fastener in the fifth threaded hole 511 and the sixth threaded hole 522 can finely adjust the position of the mounting block 51, thereby finely adjusting the tightness of the guide wire 3.
[0063] The material of the guide wire 3 is metal.
[0064] The guide wire 3 is made of metal, such as high-strength steel wire rope or stainless steel wire rope, to ensure that it has sufficient tensile strength and wear resistance.
